If you order ramen (including medium, large, oversized, and set meals) in the store on the day, you will receive one free ramen (normal) ticket on a first-come, first-served basis. In addition, when the number of free tickets reaches the planned quantity, half of the single item price of "Ramen (normal) thick and light" will be discounted from the price on the day. Free tickets will be distributed from 11:00 (some stores will be different).
Also, from October 2nd to October 14th, a "speed lottery" will be held for all ramen. It seems that you will win original goods such as a touch pen with a ramen figure. In addition, the lottery other than the winning lottery comes with a "ramen 100 yen discount ticket".
